Definitions
- the invention relates to a device for distributing thick matter, e.g. Concrete, in several conveyor lines of the gate specified in the preamble of patent claim 1 and a method for operating such a device.
- a device of this type is known for use on tunnel construction sites (DE-PS 35 06 463), in which the conveying lines can be connected with their free end to the filling openings of a tunnel opening, which are offset with respect to one another both in the circumferential direction and in the direction of the tunnel axis, and one after the other Concrete can be applied.
- the connections of the delivery line facing the pump are rotatably flanged symmetrically on a distributor plate.
- a pivotable, preferably S-shaped distributor pipe is provided, the connection of which facing the concrete pump is connected via a rotary coupling coaxially to the axis of symmetry with a feed pipe connecting to the pump and the second connection of which is connected to a on a rotating plate arranged, through the rotating plate leading to the distributor plate flanged.
- the rotary plate can be rotated about the axis of the feed pipe connection relative to the fixed distributor plate, so that the connection pipe can be connected to the various delivery line connections.
- this measure alone is not sufficient for an exact assignment.
- the frictional behavior between the rotating plate and the distributor plate changes depending on the period of use and wear of the device. Due to the different wear, material settles in the wear zones. This changes the friction behavior at the different connections, so that the connections are more or less overrun or undershot when turning further. If the through openings are not exactly aligned, an increased flow resistance or even a blockage occurs.
- steel fiber concrete there is also the problem that when the turntable is turned further, a certain amount of steel fibers is always taken along, which settle in the turning gap and build up there in more or less thick layers. This creates gaps through which the pumped concrete can bleed out. The resulting loss of fluid can in turn lead to blockages which impair the functionality of the machine.
- the invention has for its object to improve the known device of the type mentioned in such a way that, regardless of the consistency of the thick matter to be conveyed and regardless of the frictional conditions that change over the course of the operating time, an exact positioning of the rotary plate with respect to the Ver ⁇ divider plate in the prescribed passage positions is possible.
- locking cams arranged on the rotary plate at an angular distance from the delivery line connections and a locking pawl are arranged on the distributor plate, that the locking cams can be rotated in the forward direction of rotation of the rotary plate under the locking pawl and in the reverse direction of rotation against it under cursing tenders Strike the alignment of the connecting piece with the respective delivery line connection.
- the locking cams arranged on the circumference of the rotary plate expediently have a front wedge surface designed as a run-on surface for the locking pawl under the action of a spring and a sharp-edged rear surface which abuts against an end face of the locking pawl.
- the rotating plate on the distributor - Plate-facing broadside carries a rubber-elastic sealing washer provided with a passage opening for the connecting piece, with which it bears against the distributor plate while sealing the delivery line connections which are not currently aligned with the connecting piece.
- the steel fibers which are deposited between the plates are at least temporarily embedded in the rubber-elastic material without the sealing being reduced.
- the steel fibers are partially stripped again from the sealing plate, in particular if an edge, for example the perforated edges of the delivery line connections.
- a further improvement in this regard can be achieved in that in the area of the contact surface between the rotating plate and the distributor plate, the concrete constituent and steel fibers reaching radially outwards and inwards are continuously conveyed away by rinsing water circuits.
- a circumferential annular channel which can be acted upon with flushing water is arranged in the radial region between the ball slewing ring and the delivery line connections.
- a chamber which can be acted upon by flushing water and extends through the contact surface between these plates can be left out.
- a sensor on the distributor plate which is designed as a proximity switch and is arranged in a contactless manner on projections or tabs arranged at an angular distance from the feed line connections on the turntable.
- a sensor on the distributor plate which is designed as a proximity switch and is arranged in a contactless manner on projections or tabs arranged at an angular distance from the feed line connections on the turntable.
- the switching from funding line to funding line can take place according to certain criteria.
- the absolute pressure reached in the injection chamber plays a role in the case of tunnel concrete, in particular with extrusion concrete. Therefore, the turning process of the rotating plate is expediently triggered in accordance with the thick material pressure measured at the outlet of the delivery line which is currently switched through, the pumping operation also being switched off at the same time.
- the rotation of the rotary plate is triggered after reaching a certain delivery quantity transported by the currently switched delivery line or after reaching a predetermined number of strokes.
- the switching frequency between the individual turning operations can also be controlled in accordance with the speed of advance of the tunnel boring machine.
- tunnel construction the tunneling machine is regularly sealed against ingress of water by a grease chamber with steel inserts.
- the grease chamber pressure represents a back pressure against the penetrating water.
- the pump pressure is switched off each time the turning plate is turned.
- the various delivery line connections are expediently started up with the aid of a programmable logic controller in any order which can be predetermined.
- the device according to the invention can be used particularly advantageously when using extrusion concrete with steel fibers in tunnel concreting.
- precise metering of concrete into the faceplate of the tunnel boring machine is of crucial importance, since this is the only way to prevent irregularities in the concreting when driving under rivers, gravel and water from the environment.
- the invention is explained in more detail below on the basis of the exemplary embodiment shown schematically in the drawing. Show it
- Figure 1 is a side view of a rotor distributor in a simplified sectional view.
- FIG. 2 shows a top view of the rotary plate of the rotor distributor according to FIG. 1;
- FIG. 3 shows a sectional illustration of a section of the rotor distributor in an enlarged detailed illustration.
- the rotor distributor shown in the drawing essentially consists of a distributor plate 12 rigidly connected to a machine frame 10, a rotary plate 16 rotatably mounted on the distributor plate 12 about the axis 14, and a flange-mounted on the rotary plate 16 S-shaped distributor pipe 18 and a plurality of delivery lines 20 arranged at equal angular distances from one another and flanged to the distributor plate 12.
- the distributor pipe 18 is connected to the pump (not shown) via a rotary coupling 22 coaxially to the axis 14 with one to the pump leading supply line connection 24 and can be connected with its second connection 26 via a connection piece 28 arranged on the turntable 16 and through the turntable 16 to the distributor plate 12, optionally with the various delivery lines.
- connections 30 are connected to the distributor plate 12.
- locking cams 32 are arranged at an angular distance from the delivery line connections 30, while the distributor plate has a locking pawl 36 under the action of a spring 34.
- the locking cams 32 can be rotated under the pawl 36, while in the reverse direction of rotation they strike with their rear flank 40 against the end face 42 of the pawl 36.
- the rotary plate 16 is mounted on the distributor plate 12 via a ball slewing ring 43.
- the rotary plate 16 carries on its side facing the distributor plate 12 a rubber plate 46 which is ulcanized onto a steel plate 44 and which has a passage opening 48 penetrated by a nozzle part in the area of the connecting piece 28.
- the free wide side of the rubber plate 46 bears against a hard metal counter disk 50 fastened to the inner wide side surface of the distributor plate 12 and provided with through openings 52 in the region of the feed line connections 30.
- the passage openings 52 are closed by the rubber plate 46 pressed against the disk 50, so that the Concrete cannot emerge from the delivery line into the intermediate area between the two plates 12 and 14.
- the concrete arriving from the feed line 24 is conveyed in the direction of the arrows 54 into the delivery line 20 which is currently aligned with the connecting piece 28.
- the ball slewing ring 43 is separated from the area carrying the feed line connections 30 by a sealing ring 56.
- a circumferential annular space 58 which can be supplied with rinsing water via a line 60 from the side of the distributor plate in the direction of arrow 62.
- the rinsing water flows down through the ring channel 58, taking the concrete constituent and solid particles escaping there, and out through an outlet opening (not shown) into a waste water channel.
- a chamber 64 which penetrates the hard metal disc 50 and the rubber disc 46 and can be acted upon by flushing water via the line JB6 in the direction of the arrow 68.
- the rinsing water that cleans the chamber 64 is conducted via the nozzle 70 into the sewage channel.
